,To all whom it may concern:

Be it known that I, LOUIS Bins, a citizen of the United States, residing at Mendota, in the county of La Salle and State of Illinois, have invented a new and useful Bread-Raiser and Flour-Warmer, of which the following is a specification.

This invention relates to bread-raisers and hour-warmers, and pertains particularly to that class of such devices'embodying separate compartments within a heat chamber or inclosure.

The intent and purpose of the present invention are to provide means' for facilitating bread-making under all climatic conditions or to maintain the required degree of temperature irrespective of the condition of the surrounding atmosphere, and thereby prevent the least aection of the leavening process, which is essen tial to successful bread-makin g.

The invention y consists, essentially, of a cabinet or casing adapted'to be supported at a suitable distance above a base -rest Y and formed in its upper portion with a chamber having separate compartments which are closed and one adapted to receive the breadsponge, kneaded dough, or the dough panned in loaf form and the other providing a iiourreceptacle whereby heat may be imparted to the iour and avoid chilling the sponge or dough during the several steps of the breadmaking, the two compartments being sepa' rate from each other and having controlling -means related and necessary to their special service.

Thev invention further consists in the details of construction and arrangement of the several parts, which will be more fully here-t inafter describedvand claimed.

In the accompanying drawings, Figure lis a transverse vertical section of abread-raiser and flour-warmer embodying the features of the invention. Fig. 2 is a top plan view of a portion of the same broken away to show the interior construction.

Similar numerals are employed to indicate corresponding parts inthe views. V

The numeral 1 designates a cabinet or casing constructed of suitable material, preferably wood, and having a top 2 fitted thereon. This cabinet or casing will be supplied with a suitable door to gain access to the interior thereof and is supported by legs 3, connected near their lower terminals by a shelf or rest 4, having anv opening 5 therethrough near one end and below which is mounted a slide 6, movable in opposite guides 7. The interior of the cabinet or casing lis provided with a lining 8 of sheet metal, and at one side near the top a thermometer 9 'is secured and has its bulb 10 projected into an opening 11 in the cabinet or casing and continued through the lining 8. The bulb 10 closely iits within the opening 11 and has a free exposure to the interior of the said cabinet or casing, so as to be sensitively affected by the heat within the latter and correctly indicate the exact temperature.

' Supported in one side of the chamber inclosed by the cabinet or casing 1 is'a breadraising compartment 12, which has a `lower opening therein leading to a depending heatchamber 14, which projects downwardly Ithrough the bottom of the cabinet or casing 1 and snugly receives the upper end of 'a heatconveying pipe or tube 157 fitted on a lamp 16, which is removably disposed on the slide 6 and held in the opening 5 in the shelf or rest 4; At the point where the chamber 14 extends downwardly through the bottom of the cabinet or casing the latter is cut away, as at 17, and the sheet-metal lining 8 is extended over and closely surrounds the said chamber, thereby preventing the heat of the chamber ring the wood of the cabinet or casing. Communication between the chamber 14 and the heat-chamber inclosed by the cabinet or casing is accomplished by means of a series ofope-nings 18 in the said chamber 14 above the metallic lining S in the bottom of the cabinet, and removably fitted in the opening IOO partment and controlled by a slide-damper In the top 2 of the cabinet or casing, directly over the compartment 12, an opening 24 is formed,and fitted therein is a removable flanged lid or cover 25, supplied with a grip 26 for evident purposes. Surrounding the said opening 24 and at suitable distances therefrom, as clearly shown in Fig 2, are outlets or Ventilating-openings 27, having reticulated coverings 28, and leading from the said openings are diagonallydisposed ducts or conduits 2),preferably of U -shaped form,and secured against the under side of the said top 2 with their inner openings adjacent the wall of the opening 24. Also located within the cabinet or casing 1 is a flour-receptacle 30, having a depending spout 31, extending through the bottom of said cabinet or casing, and near the lower end is an internal siftingscreen 32, with which agitators 33 relatively operate and are carried by a rod or shaft 34, having bearing in an adjacent support 35 and terminating in an outer crank or handle 3G. A cap or cover 37 is removably fitted to the lower end of the spout 31, and the opposite sides of said receptacle are bent or formed to slope toward the spout 31. In the top 2 of the cabinet or casing, directly over the receptacle 31, an opening 3S is formed and provided with a cover 39. opening is to gain access to the receptacle 30, so that iour may be placed therein.

IIeat-fiues 40, 41, and 42 are formed between the outer portions or sides of the receptacle 30, the compartment 12, and the inner portions of the walls of the cabinet or casing and also between the said receptacle and chamber. Heat-spaces are also formed between the bottoms of the receptacle and the bread-raising compartment 12 and the inner part of the bottom of the cabinet or casing as well as over the top of said compartment. By means of these ilues and spaces a thorough circulation of the heated air around the chamber 12 and the receptacle 30 is permitted, and the ventilation or egress of said heated air takes place through the ducts or conduits 29. The interior of the cabinet or casing or the chamber inclosed thereby can be easily tempered by regulating the flame of the lamp 16, and it has been found that the most desirable temperature is about Fahrenheit.

In using the improved device for the purpose stated the lid or cover 25 is removed and a pan containing the sponge is placed over the opening 24, as clearly shown in dotted lines in Fig. 1. The sponge is left in such position overnight, care being taken to have the lamp 1G so adjusted as to maintain the requisite degree of temperature within the cabinet or casing, and during the time that the sponge rests upon the opening 24 the flour within the receptacle 30 is correspondingly heated, so that when the bread is kneaded after the leaven has sufficiently operated there will be no chilling effect d ue to the in- The purpose of this.

trodnction of cold flour and the continued progress of the rising will not be in the least retarded. After the dough has been kneaded it is again placed over the opening 24 until it has again raised sufficiently and is then made into loaves and panncd. The opening 24 is now closed and the panncd dough is placed upon the racks 21, warm water being first deposited iu the basin 19. The cabinet or casing is then closed and the panncd dough inspected from time to time. If it is found that the panncd dough sweats, the damper 23,Which has been heretofore closed, is opened and the chamber 12 is relieved of excessive moisture or humidity. During the treatment of the sponge and the kneaded dough before panification it is not necessary to use the basin 19, and this may be removed and not be replaced in position until the panncd dough is deposited on the racks 21.

In using iiour from the receptacle 30 a pan or receptacle is placed on the shelf or rest 4 under the lower end of the spout 31 and by rotating the agitators 88 over the sieve 32 the flour can be dispensed in such quantities as may be found necessary.

The tube or pipe 15 of the lamp 1G when applied ts snugly within the lower portion of the chamber 14; but when said lamp is removed or disconnected the slide 6 is moved downwardly and the body of the lamp let down, so as to clear the upper portion of the tube or pipe 15 from the bottom of the said heat-chamber, and afterward a reassemblage can be easily attained similar to that shown. By having the ducts 29 radiate in different directions the interior of the cabinet or casing can be more evenly tempered and a sufficient ventilation established to set up a proper combustion in the lamp.

It will be observed from the construction specified that the contents of the bread-raising compartment 12 will be free from contamination by the products of combustion, and though the improved device has been referred to as particularly applicable for bread-making it Will be understood that cake or other material can be equally Well treated.

For various uses or to adapt the parts to different applications it may be necessary to change the proportions, size, and details of construction. Such changes will be made, therefore, as fall within the scope of the invention, and it will not detract in the least from any advantages of the preferred arrangement set forth.

Having thus described the invention, what is claimed is- 1. In a bread-raiser and flour-warmer, the combination of a chamber having a metallic lining, a bread-raising compartment stationarily supported within the chamber and having bottom, top and side surrounding spaces, a flour-receptacle independent of the breadraising compartment and located in the said chamber, the said flour-receptacle being separated from the bread-raising compartment IIO by an intervening space and having a lower deliveryspout and an upper feedopening, means for heating the said chamber, and means for regulating the temperature thereof.
